Summary

To compare the two different suture knot techniques, locked and unlocked, in terms of mean on postoperative trismus and swelling after impacted mandibular third molar surgery.

Detailed description

The rationale behind conducting a comparative analysis of two different suture knot techniques on postoperative trismus and swelling following impacted third molar surgery stems from the imperative need to optimize patient outcomes and improve surgical practices. Impacted third molar surgery, while a routine procedure in oral and maxillofacial surgery, often presents challenges in managing postoperative complications, particularly trismus and swelling, which can significantly impact patients' comfort, recovery, and overall satisfaction.

Conditions

• Trismus
• Swelling

Interventions

Type	Name	Description
PROCEDURE	locking and non locking suture techniques	The participating patients will be randomly assigned into two groups, i.e. receiving locked (L) or unlocked (UL) sutures, using a lottery method. Equal patients will be assigned in both groups. In group L (Locked suturing), the flap will be repositioned and sutured with the locked technique (straight-reverse-straight) hermetically using 3-0 black silk. In group UL (Unlocked suturing), the flap will be repositioned and sutured with the unlocked technique (three straight knots) loosely using 3-0 black silk. Demographic details (including name, age, gender, contact) will be obtained and recorded on specific data collection forms. On the day of surgery before the surgery commences, measurements will be taken for trismus and swelling which will be entered on the data collection form. Trismus will be evaluated by measuring the distance between the mesio-incisal corners of the upper and lower right central incisors at maximum mouth opening in mm, using Castroviejo instrument.
